Answer:
6 cm
Step-by-step explanation:
The area of a triangle is 
, where b = base, h = height, and A = area. In this case, we're given the height as 4 cm and the area as 6 cm^2.
Let's plug in these values.
Now, let's solve this algebraically.
Step 1: Multiply both sides by 2.
Step 2: Divide both sides by 4.
Step 3: Check if solution is correct.
Therefore, the base is 6 cm. (but don't put the cm in the box because it's already there)

Answer:
perimeter of rectangle = 2(l+b)
= 2 (9+5)
= 2 X 14
= 28 cm

Answer:
The third equation: 
Step-by-step explanation:
The two points on the line are 
and 
.
Slope of the line passing through two points 
and 
is given as:
Here, and are and .
Therefore, slope is equal to, 
Now, equation of a straight line with slope m and points and is given as:
Now, if we use the 2nd form, then 
.
So, the equation is given as :
1 sec=1/10 m
5 min=300 sec
thus, 1/10 *300
=30 m
He will walk 30m in 5 min
Step-by-step explanation:
The formula for calculating a circle's circumference is πd, where π is an irrational number (3.14....) and d is the diameter of the circle.
In the circle with diameter 19.5cm, the circumference is around 3.14 * 19.5cm = 61.23cm. (A)
